DHI introduces two major new products:
• PPCH-G™   PPCH-G is a pressure controller/calibrator for gas pressure operation from 1 to 100 MPa (150 to 15 000 psi). PPCH-G's emphasis is on high end performance, minimizing measurement uncertainty and maintaining precise control over a very wide pressure range.
• GB-H-152-70M™ and GB-H-152-100M™  GB-H-152-70M and GB-H-152-100M are gas booster packages intended to be used to provide the gas pressure supplies required by DHI PPCH-G controller/calibrators for high pressure gas. Both booster packages provide a safe, simple and complete solution to the challenge of very high gas pressure supply generation.

A new FLOW technical note is available online for TYPICAL MEASUREMENT UNCERTAINTY IN GAS FLOW MEASURED BY GFS2102 GRAVIMETRIC FLOW STANDARD.
DHI Tech Note No. 6050TN09
